India needs more crops and solar energy than any other country. So you are installing solar panels in height

by

When a solar energy company offered Harpal Dagar a fixed pay for 25 years in exchange for installing solar panels on their cultivation fields, he thought it could be a scam. Today he says that his income has tripled and sleeps quieter. “Too good to be true.” That was what this Indian farmer thought when the company Sun Master proposed to install elevated solar panels on its land on the outskirts of Delhi. I could continue working the land and, in return, would receive an annual payment for 25 years. According to a report of BBC NewsDagar had lost entire crops because of the Monzones, so he accepted the installation of the panels to have fixed income. “Today I think it was the best decision I have made,” he told the British environment. Harvest food and energy at the same time. The systems that combine agriculture with solar energy generation in the same land have a name: agrovoltaic. And in the most populous country in the world they are emerging as the most promising solution to produce clean energy without sacrificing the land necessary to feed the population. The agrovoltaic part of a simple idea: take advantage of the vertical space. Instead of choosing between a crop field or a solar park, They both haveonly that photovoltaic panels are mounted on high structures, at a height of at least three and a half meters so that tractors and other agricultural machinery can pass below. India cannot do without cultivation soil. In India more than 55% of the population It depends on agriculture. As the country approaches the 1.7 billion people in 2050, it will have to produce about 350 million tons of grain At the same time, India has pledged to meet ambitious climatic objectives that will require dedicating solar and wind energy between 55,000 and 77,000 square kilometers of land. According to a report from Mongabay Indiaagrovoltaic would resolve this paradox of “food security vs. access to energy”. Not everything that shines is gold. Sun Master pays Harpal Dagar about $ 500 per hectare per year, plus a monthly salary of 170 dollars for the maintenance of the panels. Dagar cultiva turmeric, which benefits from the microclimate created by the solar panels. Its shadow protects the cultivation of extreme heat and decreases water evaporation, reducing irrigation needs. It is not always beneficial. Depending on their disposition, solar panels reduce between 15 and 30% the light that reaches plants. This makes basic cultures that need a lot of sun, such as wheat, rice or soybeans, are not viable. Anand Jain, another farmer who has experienced with the system, says he succeeded with strawberries and tomatoes, but “the cauliflower did not work so well.” The green leafy vegetablesginger and some flowers have also benefited. The slow takeoff from agrovoltaic. The adoption of agrovoltaic in India is being slow, especially compared to China, which has 12 times more projects in operation. Incompatibility with some crops is one of the problems, but there is an even greater financial problem: raising panels more than three meters from the ground has a price. The installation of an agrovoltaic system is between 20 and 30% more expensive than that of a conventional solar park. Small farmers cannot afford these systems, so they depend on companies with capital that want to rent their land with a 25 -year contract. Technology will solve some challenges. For companies to be willing to assume that risk, more efficient and profitable systems are already being developed. “Farm-Forward” solar panels with More space between panel ranks to maximize the entry of light and further facilitate the step of machinery. And new software to simulate how much light and heat receives each sheet, how it affects photosynthesis and, ultimately, what performance of the harvest. The potential is simply gigantic. A GIZ technical report He estimates that agrovoltaic in India can point to a capacity of between 3,156 and 13,803 gigawatts. To put it in perspective, the total installed capacity of photovoltaic energy worldwide is 2 GW. In Xataka | One of the most arid areas in China is reverde. The reason: a plant with seven million solar panels

Gemini’s arrival to Wear OS 6 is great news. The question is whether an experience at the height

by

Samsung just present his smartwatches Galaxy Watch8 and Watch8 Classic. A priori we might think that these watches simply embody the annual update of their hardware to which it and many other companies have accustomed us. However, The Galaxy Watch8 propose a differential benefit that, therefore, it is worth not overlooking: they are the first smart watches in the market that They incorporate Wear OS 6 with Gemini. As we anticipate from the head of this article, in our opinion the arrival to these smartwatches of the artificial intelligence (AI) of Google is good news. And it is because presumably will have a deep and positive impact on our experience. The integration of this technology into a device that users usually always carry on, and that, in addition, resides in a very accessible area, greatly facilitates its use. In fact, what Samsung proposes to us on paper paints very well. And if we turn to Gemini we can interact with these smart watches using natural voice commands to, thus control apps such as Samsung Health, the calendar or the clock. We can also use Gemini to find a nearby location, such as a pharmacy, or to send text messages. Interestingly, the SOC proposed by these watches is the same that incorporates the Galaxy Watch Ultraso we suspect that it will be possible to update the operating system of this last device to Wear OS 6 with Gemini. Our experience with Gemini is in the hands of the SOC exynos w1000 This chip is very special. And it is because it is one of the first integrated circuits manufactured by Samsung using Gaa photolithography (Gate-alall-around) 3 nm. The purpose of this innovation is to outdo Finget technology in a crucial parameter: watt performance. The semiconductors with Finfet transistors began to be manufactured on a large scale in the early last decade, so it is a mature technology that TSMC, Intel and Samsung know very well and will not easily abandon. Even so, in the future GAA transistors will reign. The Exynos W1000 SOC will be largely responsible for the experience that Gemini will offer us at the Galaxy Watch8 and Watch8 Classic Anyway, there is no doubt: the soc Exynos W1000 It will be largely responsible for the experience that Gemini will offer us in the smartwatches Galaxy Watch8 and Watch8 Classic. And probably Also at the Galaxy Watch Ultraas I mentioned a few lines above. We can anticipate that we will soon put these smart watches to the test and confirm if Gemini really offers us an experience at the height of what we can expect. The latency in this scenario of use is crucial. In any case, on paper we can be reasonably optimistic. And it is that the specifications of this SOC, beyond the lithography that Samsung has used to manufacture it, are quite ambitious. In fact, it incorporates a Cortex-A78 nucleus to 1.6 GHz and four Cortex-A55 nuclei to 1.5 GHz that work side by side with a main memory map of 2 GB of type LPDDR5. The graphic logic, which also has a crucial role in the field that interests us, is a Mali-G68 MP2. Paint well. Samsung says that this soc is Up to 3.7 times more powerful That the previous one, the chip Exynos W930in a multihilo use scenario. We will see it. We hope to tell you much more about the experience proposed by Gemini in these smartwatches coming soon. Image | Xataka In Xataka | Intel is already manufacturing chips on the Intel 3 node. The competition with TSMC and Samsung starts here

The rumors placed the power of Nintendo Switch 2 at the height of PS4 Pro. ‘Cyberpunk 2077’ arrives to solve doubts

by

What generation belongs Nintendo Switch 2. That was one of the unresolved questions about the new Nintendo console. Since the company left the Power War After the disaster of Game Cubeit has gone free and, although technically it would be the first tenth console, it is also logical to put it in the sack of the ninth generation (PS5, Xbox Series x and SERIES s). Perhaps this generations has ceased to make sense when they exist Consoles ‘Pro’but it serves to get an idea of ​​what are the like, at least in terms of power, which each machine has. Answering this in the case of Switch 2 is even more complicated because … we don’t know almost anything about your processor. But with the console in hand, we can get a better idea of Where is Nintendo Switch 2 next to its rivals. And the game that best exposes the power of the new switch is’Cyberpunk 2077‘. It is also the one that surprised me the most and the one that demonstrates what can be done with this hardware if the weapons it offers well Nvidia and its image reconstruction. “The Switch 2 chip does not resemble anything we have created before” From the announcement of the console on April 2 with A GAME RETA among which there were versions of other consoles such as’Final Fantasy VII Intergrade‘,’Yakuza 0‘,’Hitman‘, a better version of’Hogwarts Legacy‘,’Street Fighter 6‘And the aforementioned’ Cyberpunk 2077 ‘, began to tote about the power of the console. After several comparisons, it was speculated with the possibility that Switch 2 be like a Ps4 pro. This, although it may seem little, is considerable because we are talking about A very low consumption machine which is compatible with state -of -the -art technologies (VRRfor example) and that can work without being connected to the current. Based on the filtered and speculated characteristics of the Nvidia chip that mounts the console, a GMLX30-A1 manufactured by Samsunga user in Reddit He created a very interesting thread by renovating the estimated power of the machine and comparing it with other consoles. While Gflops are very similar to those of a PS4 Pro, the bandwidth was considerably less than that of the Sony console. It is something that gave rise to that perhaps Switch 2 would not be so powerful, but even without concrete data of the processor’s frequencies, you have to trust the tests of these first games and what has recently commented Jensen HuangCEO of Nvidia. Nintendo has been creating videos in which developers and members involved in the system share their impressions of Nintendo Switch 2. All are quite vaguewithout much concrete data, and Huang’s is no different. However, it does leave some pearls. Beyond that claim of “the Nintendo Switch 2 chip, it does not resemble anything we have done before”, the interesting thing is that it confirms that the console can handle rays of hardware and the SOC has AI processors “dedicated to improving the sharpness in real time.” That is, although the generation of this Soc It is not the most leading, Nvidia has introduced the necessary processes to climb the image from a lower native resolution in the personalized chip (what the DLSS) and the processors for the Hardware Raytraction. ‘Cyberpunk 2077’, Switch 2 exponent Ok, that says the CEO of the company that created the Switch 2 soc and we already know that there are always inflated statements and marketing in these things, but … What do the games say? In the video we leave at the beginning of the article, you can see the first minutes of ‘Cyberpunk 2077’ running in ‘quality’ mode when the console is connected to the dock. The sensations are very good and it shows that CD Projakt, the study responsible for the game, has done a great job These weeks. Because? Because in the demo that We could try a month ago in Paristhe performance in desktop mode was quite poor, with constant falls in the rate of Frames For the second. In the final version, it is much more stable and, above all, it looks very good on both TV and, above all, on the console screen. It is where it shines, in my opinion, due to the enormous difference between this version of switch 2 and, for example, that of a similar system: Steam Deckalso Use image climbing technologiesbut with a more blurred result in general. But a good way to really appreciate where Nintendo Switch 2 is about its rivals, is this video of the channel ‘THE BIT Analyst‘. In it, compares Nintendo Switch 2 with PS4 Pro and with the weakest console of this generation, Xbox Series S. does it in ‘performance’ mode and ‘quality’ on all platforms and conclusions are very interesting. The first, the resolution. Thanks to DLSS, it reaches 1080p In both desktop and laptop mode in ‘quality’ mode, recessing from different base resolutions already 3 fps. In ‘Performance’, the 1080p are maintained in desktop, but on the lower screen to 720p. The frame rate in this mode rises to 40, but is not entirely stable. In consoles, yes, it goes to 60 in this way. The user states that, thanks to DLSS, Switch 2 maintains an image quality comparable to the versions of PS4 Pro and Xbox Series S, with better textures and effects such as the Environmental occlusion in the Nintendo console with respect to these two competitors. It also compares with PS5, the Nintendo hybrid is quite well stopped, although with notable differences in the quality of some parameters and, above all, a higher resolution in the Sony console. The summary is that it is a very solid versionsomething that can also be seen in other games launched for the machine such as the aforementioned ‘Yakuza 0’ or ‘Street Fighter 6’, both a midpoint between PS4 and PS5, and superior When seen in the version of Xbox Series S. Said this, I am clear that Nintendo Switch 2 … Read more

The radar satellite at a higher height ever created

by

At 36,000 km altitude, in the geostationary orbit, China operates the “Ludi Tance 4-01” satellite. Released in August 2023is the first synthetic opening radar deployed at this point, which gives China a unique permanent observation capacity on a third of the earth’s surface. Freshly declassified. Chinese scientists have Recently revealed The design and capabilities of the Ludi satellite, which had been kept secret until now. Officially designed for weather observation, earthquake monitoring and natural disasters prevention, their details have put on alert to rival countries such as the United States. The United States Space Force rejects the Chinese narrative. Instead of a satellite for civil use, he believes that it is designed for high resolution recognition in the Asia-Pacific region: a powerful spy satellite that allows both civil applications and the collection of military intelligence. The reason for its height. Ludi is, Like the Spanish satellite Paza synthetic opening radar (SAR). But unlike peace, it is the first and unique Sar that operates in geostationary orbit. Located 36,000 km altitude, the Chinese satellite is synchronized with the terrestrial rotation to observe the same region continuously. And not optical, so it can cross the clouds and follow night objects. Ludi reaches a resolution of approximately 20 meters. While it is a lower resolution than the sub -metric of some spy satellites of the low orbit, from the geostationary orbit, Ludi can monitor around a third of the earth’s surface, specifically in the Asia-Pacific region. The technical details. The satellite was launched with its antenna initially folded. To achieve a useful resolution at so much distance, LUDI integrates numerous phase matrix emitters, which can be coordinated in unison. This “beam synthesis” technology allows multiple microwave beams to be combined in space to act as a single very powerful radar beam, which makes it possible to obtain high quality images. Only China. The launch of the Ludi in August 2023 marked the beginning of a new class of Earth’s observation platform. American scientists had pursued the idea of ​​radar surveillance from the geostationary orbit since the Cold War, but technical obstacles maintained all those plans on paper. China has succeeded. And Ludi is alone one of the Chinese satellites yaogan that operate in geostationary orbit. Image | Cast In Xataka | For the first time we have seen a photo taken by the US ultrasecreto space plane.

Valencia faces a serious problem with housing. So someone has had an idea: build more height

by

Tecnocasa recently published A report in which the thermometer to the Spanish real estate market, a theoretical exercise that allowed him to obtain two revealing data: in just one year the demand for housing has grown up on average 39% In Spain while the offer undertook the opposite road, retreating more than 9%. The result is a tensioning market, in which the floors last a few weeks or days (even hours) announced in real estate agencies before finding tenant or buyer. In Valencia, an idea has emerged to alleviate that problem and reinforce its public housing offer: allow buildings to gain height, a formula with which they calculate that the city could win More than 70,000 floors protected What happened? That in Valencia has been on the table An idea New to reinforce your housing park. At least the protected housing. A few days ago the Socialists proposed in the City Council of the City Council to retouch the local ordination (PGOU) so that the city buildings grow to the top. Literally. His idea is that the blocks can raise one or two plants their height. The plan He advanced it The country Wednesday, before the commission; But from the PSPV they recognize that he did not obtain the necessary support, so at least for the moment he will stay in that, an idea about the table to face the housing problem. “The PP has rejected our proposal”, Explain The socialist mayor Elisa was worth. Click on the image to go to Tweet. What have they raised? “Raise buildings to gain public housing”, summarize The PSPV of Valencia. The idea is simple: modify the PGOU to upload the city blocks one or two levels. The socialist group has already made accounts and calculates that if an extra plant was added to all buildings, 86,644 homes would leave, a large residential park also distributed throughout the municipality. As part of these constructions are protected by their heritage value or are located in Valencia neighborhoods in which height cannot be gained, the PSPV has retouched that initial figure, but the result remains considerable. “If we subtract 20% for understanding that in the historical centers and protected buildings you will not be able Explain Valía to The country. That (more than 70,000 new floors) is the figure that PSPV presumed this week in networks, where he claimed that his proposal “would avoid expulsion and uprooting.” Why such a measure? The PSPV plan is focused on the creation of protected housing (both for rent and sale) in a territory that dealt with the offer shortage and the price increase. In January the Polytechnic University of Valencia (UPV) published A report that helps to understand much better The situation From the capital of Turia: in five years the prices of the new work have triggered about 80% and the offer was reduced by 83%. Things have not been better in the rental market, which became more expensive. “What we have before us is a tsunami of epic dimensions and all administrations must act in a coordinated, effective and quickly, The director explains of the Chair of the UPV Housing Observatory after remembering the forecasts at the state level. “We estimate that more than 80% of the current demand fits in the public protection house, so the determined commitment to the construction of this type of housing is strategic.” And how do you want to do it? The PSPV proposal is not entirely new and there are other cities in which they have already been activated similar solutionstaking advantage of the ‘Flight Law’. In Valencia the idea is that it is the communities of owners themselves that can promote the ‘stretch’ up the buildings with one or two extra plants. The resulting floors would be added to the Public Protection Housing Park, which among other things would allow it to extend it to “consolidated neighborhoods”, Valía points out. The PSPV plan also includes an extra advantage for neighbors communities. In a city with an aged real estate park, in which A notable percentage From the houses it has more than four decades, the communities of neighbors would obtain from the extra buildability some resources that would allow them to modernize their blocks. Are there more cases? Yes, Valencia is not the only one that has been fixed in that formula. In Barcelona, ​​licenses have been granted to lift floors that increased the buildability of existing buildings. In 2017 it was estimated that in just three years they had benefited from that possibility (the traces) about thirty buildingswith licenses for 120 floors. Madrid too It has varied Over the years the maximum height of its buildings and the Balearic Islands leave another recent example. Palma already added in September 70 requests of buildings to grow in height and add 589 floors of limited price.
